Across the world, everyone is using the metric system of measurement, while the US is using a different system. If you wish to purchase something online from the US, digits may be unfamiliar to you, or you may not comprehend the linguistics used in a book by perhaps an American author. For convenience and simplicity, I have made this petition to use an international system of measurement. Not ounces, but litres. Not miles, but kilometres. Not feet, but meters. Not pounds, but kilograms. Sign this petition, make a change. This is the first step we all can take.
